It sounds like your fast yesterday was quite long! (If you meant 4:40 PM, that would be about 7 hours, which is a good start. If you meant 4:40 AM the next day, that’s about 19 hours — which is pretty advanced!) For menopause, we usually recommend starting gently with 12–14 hours and slowly increasing only if it feels good. Long fasts (over 18 hours) can sometimes spike cortisol, which we want to avoid.

In short: Consistency is more important than extreme fasting. Even moderate fasting daily (like 12–14 hours) can deliver amazing results over time.
